You wouldn't expect this from a company like about.com but it seems to
be true.

I was visiting
http://scifi.about.com/od/merchandis...for_XFiles.htm
and suddenly I found the well known popup.

Quick trawl trough the source at I suspect this script:
http://an.tacoda.net/an/11775/slf.js

This in turn seems to handle the popup window.

I know that companies like tacoda, doubleclick and all the others
absolutely don't give a **** what kind of banners they publish but
somehow I'd expect differently from a company like about.com.
